Shared project files

Use these unchanged files in both Bad and Good. Install the imported packages in the project: Vue, plus vue-router or Pinia where shown. Follow any version-specific support note. The entry root makes the component relationship explicit.

main.ts

import { createApp } from "vue";
import Root from "./App.vue";
createApp(Root).mount("#app");

index.html

<div id="app"></div>
<script type="module" src="/main.ts"></script>

Bad

window.innerWidth runs during setup, where an SSR environment has no browser window.

App.vue

<script setup lang="ts">
const width = window.innerWidth;
</script>
<template><p>Content</p></template>

Good

Initialize a ref to a server-safe value and read window inside onMounted, which runs after client mounting.

App.vue

<script setup lang="ts">
import { onMounted, ref } from "vue";
const width = ref(0);
onMounted(() => { width.value = window.innerWidth; });
</script>
<template><p>Content</p></template>

The Good files demonstrate the change described above; other diagnostics can still apply to the complete project.
